ABSTRACT:
An electrophotographic photosensitive material in which organic photoconductor is sensitized by a compound represented by the formula, ##STR1## wherein A, B, D and E represent independently a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a phenyl group or a 5- or 6-membered heterocyclic ring residue, and at least two of them represent a phenyl group; F is an alkyl, phenyl or styryl group; m is a number of 0 or 1, and n is a number of zero, 1 or 2, provided that when m is 1, n is 0; and X.sup..crclbar. represents an anion residue, has a high sensitivity to the whole range of visible light as well as to the infrared rays of up to around 1,100 nm, and is stable in the potential characteristics such as surface potential and dark damping factor and capable of separation photographing by use of a color separation filter.
